My invention relates to cork and stopper Fig. 2 is a view, similar to view 1, but showpullers or extractors and has more particuing the parts in their relative positions at the lar reference to a manually operated device time the entering screw has been inserted or of this type that is characterized by the proscrewed into the cork or stopper the desired 5 vision of an entering screw which is driven distance.v i

Fig. 1 is a vertical side elevation of an ex- As before stated the shank of the entering 45 tractor that is constructed in accordance with screw is positioned'for movement in the elonmy invention, the parts being shown in their gated bore 6. This shank has transverse or normal position which is the position in which lateral wings 12 at its upper end by which they should be disposed when the point of the the structure may be rotated, and the interentering screw is to be inserted in the cork or mediate portion of the shank is provided with 50 stopper. a series of rack teeth 13 that are in the form of annular ribs extending around the shaft 14 of the shank. The diameter of these ribs is such as to permit their peripheries to freely engage with the walls of the bore 6 and thereby guide the shank and the entering screw in the manner described. At its lower end the shanki sreducedas at 15 and beyond the reduced vportion the memberis merged into a screw 16 terminating at its lower ent in the impaling point 1?. This lowersection of the shank is similar to the ordinary cork screw.

The lugs 7 are bifurcated by providing a vertical slot passing inwardly from their edges and these slots continue through the block 8 and the stub 5 and open into the bore 6 sothat-guides 18 are provided that are alin- .ingand'. diametrically oppositeeach other in the. body of the structure. Operating a ms 19 are positioned in guides 18 and arepivotally mounted upon pins 20 that pass trans- ,versely through the bifurcated portions of .thelugs 7, so as to permit armsto hinge on said pins. The ends oi the armsadjacent the pins are enlarged nto disk-like form and their edges are provided with teeth 21 so that these enlarged ends of the arms present the 'form of small se mental ormutilated ears 7 b D or pinions. The diameter of these gear-like formations of the arms is such that the teeth project through the vertical slots :18 and intothe bore.6.to intermesh withtheracklike formation of shank in the manner shown inFig. 2, so that by movingthearms in one direction or other the shank is moved in the opposite direction or longitudinally in its bearing. I

In=usingthisdevice the socketlO is placed upon the upper end ,or neck of the vessel and the impaling point 17 inserted into the cork or stopper. 7 The arms should'be in the position shown in Fig. 1, that is, pendent upon the pins 20 andalongside thesocket. The shank is now rotated by turning the wings 12 and the screw portion v16 ofthe shank is moved into the cork or stopper. This movement, of course, will-drawdown the shank and by means otthegearvand rack construction 'the arms 19Ybecome elevated to theposition shown in ,Eig. 2. Thebottle or v vessel should be placed upon arigid support,

and then by grasping the arms with both handsithe operator, by pushingthem down,

will cause the shank to moveupwardlythus withdrawing the cork from the vessel because the socket 'is' resting upon the lip of 'the discharge orifice. It will he found that very little exertion on the part of the operator is required'to extract the cork orstopperin body having an elongated boreat one end and an alining socket at the opposite end .that isadapted to engage ajbottle neck, an
